The body temperature of tuatara is lower than that of other reptiles, ranging from 5.2–11.2 °C (41.4–52.2 °F) over a day, whereas most reptiles have body temperatures around 20 °C (68 °F). [81] The low body temperature results in a slower metabolism.
The study of birds is called ornithology. Birds are feathered theropod dinosaurs and constitute the only known living dinosaurs. Likewise, birds are considered reptiles in the modern cladistic sense of the term, and their closest living relatives are the crocodilians.

Penguins are a group of aquatic flightless birds from the family Spheniscidae (/ s f ɪ ˈ n ɪ s ɪ d iː,-d aɪ /) of the order Sphenisciformes (/ s f ɪ ˈ n ɪ s ə f ɔːr m iː z /). [4] They live almost exclusively in the Southern Hemisphere: only one species, the Galápagos penguin, is found north of the Equator.
Members of this group have also been called "hawk-buzzards". [6] The proposed new genera Morphnarchus, Rupornis, and Pseudastur would be formed from members of Buteo and Leucopternis. [7] Members of the "Buteogallus group" are also called hawks, with the exception of solitary eagle species. Buteo is the type genus of the subfamily Buteoninae.
